New Barton Block Range Series 6: 64 mm cruiser blocks

This range of high load cruiser bocks are of rugged construction, featuring high quality injection moulded side plates with all load-carrying components from 316 grade stainless steel. Side plates are through-bolted and riveted for added strength and security.

This good looking and versatile range is designed for use on larger cruising and racing yachts. All are designed for ease of use with our ball-bearing mainsheet traveller systems.

Ball bearing blocks
